A week ago I heard on youtube a very accomplished shooter - I forget just who - say he applies equal grip pressure with both hands, not 40% with his strong hand and 60% with his support hand.
Recently on this board I read Paul Sharp's post about applying support-hand grip pressure front to back (low on the front of the grip, high on the back) to help control muzzle flip.
Yesterday I went to the range and increased the grip of my strong hand, and I found that it helped me control the muzzle flip. I was still shooting my Glock 19 to the right (I'm a lefty shooter) but not as far to the right as before.
So I'm wondering: Why do most shooters advocate a 40/60 grip pressure ratio, and why do some, like Alfred League, argue that if too much strong hand grip pressure is used a shooter will pull his/her shots to the side?
